The tunnel was carved by hand through which in the past the animals had to be unloaded so that they could pass through. Now, it is somewhat wider and allows tractors etc. to pass. Without a doubt, it is the most spectacular area of the route, with impressive vertical precipices.

The viewpoint is in the heart of the Redes Natural Park. From Bezanes there is a path that leads to the braña de Brañagallones and that will allow you to approach this natural balcony, with one of the best views of the park. The masses of La Rapaona and Peña del Viento stand out.

Be careful, the climb from Belerda is really strong, sections of 23% and terrain in fair condition, forest track for livestock use within the Redes Natural Park. Only access by walking or cycling.
